我用Go编写了这个API,它使用excelize创建一个.xlsx文件,从数据库中获取的数据,我想上传到私有GCS存储桶。但问题是在我上传文件后,它说文件类型不是 。application/zipapplication/vnd.openxmlformats-officedocument.spreadsheetml.sheettype Connection struct { Credential string BucketName string APIKey string ProjectID string AccessToken string BaseURL string GcpCredential *google.Credentials}func (conn *Connection) Upload(url, name string) (err error) { ctx := context.Background() client, err := storage.NewClient(ctx, option.WithCredentialsFile(conn.Credential)) if err != nil { return err } err = write(client, conn.BucketName, name, url) return err}func write(client *storage.Client, bucket, object, url string) error { ctx := context.Background() f, err := os.Open(url) if err != nil { return err } defer f.Close() wc := client.Bucket(bucket).Object(object).NewWriter(ctx) _, err = io.Copy(wc, f) if err != nil { return err } if err := wc.Close(); err != nil { return err } return nil}//In other file, generate excel file and upload it using above codexlsx := excelize.NewFile()//setup file content...//save to local machine located in uploadURLerr = xlsx.SaveAs(uploadURL)//then upload to GCS bucketerr = h.Googlestorage.Upload(uploadURL, fileNameInGCS)if err != nil { SendBadRequest(w, err.Error()) return}//then generate signed URL for client to access the file这是一个问题,因为当我生成文件的签名URL时,它被下载为.zip文件,而不是.xlsx。"{file path in bucket}.xlsx?Expires=1617698911&GoogleAccessId={googleAccessID}&Signature={someGeneratedSignature}"如何解决此问题?我上传文件的方式有问题吗?

您可以使用 ObjectHandle.Update 函数
_, err := client.Bucket(bucket).Object(object).Update(ctx, storage.ObjectAttrsToUpdate{ ContentType:"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", })
